Patented Nov. 20, 1934 UNITED STATES SILL BRICK Richard Rimmer,

Ainsdale, England Application November 14, 1932, Serial No. 642,630 In Great Britain December 24, 1931 4 Claims.

This invention relates to bricks for sills of the kind having a groove in the upper surface, drained by holes cut through the sill to points outside the wall so as to prevent Water from entering the Wall.

It has previously been proposed to form the upper surface of a stone or cement Window sill With a V-shaped groove which is partly filled by a triangular tongue on the Wood sill, and which is drained by a metal tube leading through the sill from the apex of the V to a groove on the underside of the sill outside the Wall.

According to this invention the base of the groove in the upper surface of the brick is sloped down towards the front, and communicates at its front end with the hole or holes cut through the brick.

A preferred form of brick according to my invention will now be described With reference to the accompanying drawing in which Figure 1 is an end elevation of the brick and Fig. 2 is a plan View of the same. Fig. 3 is a perspective View of the brick.

The brick is provided at the top With a groove A which is preferably 2 inches Wide. This groove slopes down towards the front and is preferably 1/4" deep at the back and 1%; inch deep at the front. The groove A is drained at its front side by two holes D communicating With a drip groove E. The Wooden sill rests on the ledge F and bridges the groove A so that any water drawn under the Wooden sill, passes into the groove A and drains out of the holes D.

By this means Water is prevented from getting down the cavity of the brick-Work.

The brick has a sloping projection B at one end with a groove H in its upper surface and a corresponding recess at the other end C, the projection B of one brick being adapted to interlock With the recess C of the next adjoining brick.

The fillet G is to prevent draught getting through to the room.

The brick may be of any convenient length, but is preferably about 91/2 long x 6% x 31/2" on end section.

The brick may be of terra cotta, cement or any suitable material.

I claim:-

1. A sill brick comprising a top, a collecting groove in said top, for collecting Water beneath the Wooden sill, said Wooden sill resting on said sill brick, the base of said collecting groove being inclined to the front, an underside to the brick, a drip groove in saidv underside, said (Cl. 'l2-98) drip groove being spaced from the Wall of the building, said collecting and drip grooves being connected by a hole for draining the lcollecting groove.

2. A sill brick comprising a top, a collecting so groove in said top for collecting Water beneath the Wooden Window sill, said Window sill resting on said sill brick, the base of said collecting groove being inclined to the front, a bottom to the brick, a drip groove in said bottom, said drip groove being spaced from the Wall of the building, the collecting and drip grooves being connectedby a plurality of holes for draining said collecting groove.

3. A sill brick comprising a top and bottom, a collecting groove in said top for collecting Water beneath the Wooden window sill, said Wooden sill resting on said sill brick, the base of said collecting groove being inclined to the front, a drip groove in the bottom of the brick, said drip groove being spaced from the wall ofthe building, means connecting the base of the collecting groove With the drip groove for draining the collecting groove, ends to the brick, a projection on one end, the top of said projection being inclined and connecting With the drip groove, a locking groove in said projection, a recess in the other end of the brick, the projections and recesses ci adjoining bricks interlocking.

4. A sill brick comprising a top, a bottom and ends, a collecting groove in the top for collecting water beneath the Wooden sill, said Wooden sill resting on the sill brick, the base of said collectingv groove being inclined to the front, a drip groove in the bottom of the brick, said drip groove being spaced from the Wall of the building, -means formed through the brick connecting the base of the collecting groove with said drip groove for draining the collecting groove, a projection at one end of the brick, the top of said projection being inclined and connecting with the drip groove, a'locking groove in said'projection, a recess in the other end of the brick, the projections and recesses of adjoining bricks interlocking, and a raised fillet on the top of the brick at the-back there-y of for vstopping draughts.
